[TowerTalk] Push Up Mast

[David Gilbert]

You can buy 3 inch or 4 inch diameter aluminum irrigation tubing in 
lengths up to 60 feet long from Rain-for-Rent on the south side of 
Tucson.  I don't remember the address off the top of my head but I think 
it's a bit east of Kolb and just north of the freeway.  I bought a 40 
foot length of the 4 inch stuff and was easily able to walk it up to a 
vertical position.  You can probably talk them into delivering for free 
if you're willing to wait until they need to send a truck in your area.  
I bought new tubing with a .070 inch wall thickness (they also sell .052 
inch) and it wasn't overly cheap, but you can also buy used tubing from 
them when they have the size you want on hand.

I'd attach a pulley and rope to the top of the tube before raising it so 
you can hoist up the dipole after you have everything secured.
